1、配置工程
注意：Team这个地方必须是企业的或者是公司的，不能是Personal Team。如下图
2、设置Capabilities
设置完了之后，左侧会出现 XZHealthDemo.entitlements。如下图：
3、设置 Info.plist
注意：描述语句只能写 "some string value stating the reason"，其他的都会崩溃。
Privacy - Health Share Usage Description // 读取权限
some string value stating the reason
Privacy - Health Update Usage Description // 写入权限
some string value stating the reason
或者
<key>NSHealthShareUsageDescription</key>
<string>some string value stating the reason</string>
<key>NSHealthUpdateUsageDescription</key>
<string>some string value stating the reason</string>4、错误解决
出现错误：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthUpdateUsageDescription must be set in the app's Info.plist in order to request write authorization for the following types: HKQuantityTypeIdentifierStepCount'解决 同 3 设置Info.plist
5、代码编写
1>判断设备是否支持 HealthKit 框架
func isHealthDataAvailable() -> Bool2>判断是否支持健康记录，iOS 12.0 以上系统
func supportsHealthRecords() -> Bool3>某一种健康类型的支持状态
func authorizationStatus(for type: HKObjectType) -> HKAuthorizationStatus
HKAuthorizationStatus 有3种结果：
notDetermined // 不确定
sharingDenied // 不允许
sharingAuthorized // 允许4>请求读写权限：在用户读取和写入数据之前，需要请求是否有权限。
要自定义显示在授权表上的消息，请在您的应用程序中设置以下键 Info.plist 中：
设置NSHealthShareUsageDescription键，自定义用于读取数据的消息。
设置NSHealthUpdateUsageDescription键，自定义用于编写数据的消息。
func requestAuthorization(toShare typesToShare: Set<HKSampleType>?, read typesToRead: Set<HKObjectType>?, completion: @escaping (Bool, Error?) -> Void)5>是否有读写的权限，iOS 12.0 系统以上
func getRequestStatusForAuthorization(toShare typesToShare: Set<HKSampleType>, read typesToRead: Set<HKObjectType>, completion: @escaping (HKAuthorizationRequestStatus, Error?) -> Void)6>保存某个数据
func save(_ object: HKObject, withCompletion completion: @escaping (Bool, Error?) -> Void)7>保存多个数据
func save(_ objects: [HKObject], withCompletion completion: @escaping (Bool, Error?) -> Void)8>执行查询方法
func execute(_ query: HKQuery)9>停止查询
func stop(_ query: HKQuery)导入HealthKit框架
